Erm, this topic is probably gonna be a hot topic of debate if this goes on.

But still I am not totally convinced that good barista is any more important than good coffee. Ever tried making coffee from stale char-roasted coffee from the grocery store?(Just ask this out of curiosity, I tried it and ever since I believe coffee is definitely on the top important list) It's so bitter as the chinese medicine I used to have as a kid, no matter what I tried.

Of course, I am probably not a very good barista and it's probably due to my nature of low bitterness intolerance. Not to mention that I am pretty sensitive that the stale coffee smell in the restaurant can make me nauseous with headache.
I am really having a hard time believing that the barista that is using good coffee and good equipments like intelli or 49th will produce coffee worse than the grocery coffee. Even if it's a 10 sec gusher or made by above boiling point water, it sure can't beat the bitterness/staleness I got from char roasted coffee in my experience.
True, without barista, the coffee can't brew itself. What's on the flipped side of that coin?=PI can imagine three handsome baristi showing off their muscle in front of the machines

We are trying to compare the importance here, not the absence of any of them.

A mighty barista will know that he can't surpass the bad beans. =P
I would rate barista *very* slightly lower than coffee, but above grinder and machine. So it would be Coffee>Barista>Grinder>Machine.
I guess it would depend what bad barista or bad coffee means to each of us also. So far, the worst coffee I ever encountered is the *$ dark roasted & SBC "medium" roasted coffee from the grocery store & literally charcoal black decaf bean from local roaster. There might be barista that does not know how to make great coffee, but as long as they know the basic steps of preping espresso, it cant be any worse than spoiled beans.
